X-ray are produced in an X-ray tube operating at a given accelerating voltage. The wavelength of the continuous X-ray has values from. (a) `0 to oo`
(b) `lambda_(min) to oo, where lambda_(min) gt 0`
(c ) 0 to `lambda_(max), where lambda_(max) ltoo`
(d) `lambda_(min) ot lambda_(max)`, where `0ltlambda(min) lt lambda_(max) lt oo`
